In order to solve the problems of single communication mode and low communication rate of an agricultural Internet of Things integrated gateway, the invention provides an agricultural Internet of Things communication method and device based on wideband-narrowband integration, and the method comprises the following steps: setting a plurality of sensor nodes at a target agricultural environment monitoring position; acquiring sensing data acquired by the sensor nodes, and storing the sensing data in a local data file; performing data fusion on the sensing data to be transmitted; determining the data volume of a sensing data fusion result according to a preset threshold value, when the data volume of the sensing data fusion result is larger than the preset threshold value, transmitting the sensing data fusion result to a server by using a wideband network and by calling a corresponding communication protocol, and otherwise, transmitting the sensing data fusion result to the server by using a narrowband network and by calling a corresponding communication protocol. According to the invention, data fusion and network bandwidth adaptive distribution are carried out on the sensing data, so that wideband-narrowband integrated communication transmission is realized.
Description
technical field [0001] The invention relates to the technical field of Internet of Things communication, and more particularly, to an agricultural Internet of Things communication method and device based on broadband and narrowband fusion. Background technique [0002] In the application environment of the agricultural Internet of Things, due to the many types of sensors on the market, the types are complex, the interfaces are incompatible with each other, the interoperability is poor, and the network communication methods are various, so the bandwidth of different networks cannot be efficiently utilized. In the agricultural Internet of Things environment, the agricultural Internet of Things intelligent gateway that supports a variety of network communication methods and sensor interface standards for broadband and narrowband integration has become a problem that the industry is concerned about. [0003] At present, none of the agricultural IoT integration gateways on the ma...
